2001 Grand Am GT - RPMS bounce, car jerks and stalls

This has been going on for a month....right after i picked it up from being inspected, drove it for 2 days and then the problem started. Out of the blue, the rpm's were bouncing, the car was jerking and when i got to the next red light it stalled. Got it started and drove it home and it jerked the whole way and ended up stalling again. Had it towed. The mechanic could not get it to act up so had no idea what it was and had me pick it up. (they suggested putting dry gas in it and i did as soon as i got it). A couple days later it happened again and i drove it back to the mechanic....this time they changed the fuel filter....took it home and it acted up again the following morning.....took it back to the mechanic and they replaced the fuel pump then drove it 70 miles and everything was ok.....until i got back in it...drove it another 70-so miles and it started jerking around again and eventually stalled. Towed again...has been at the dealer the last two weeks and they still don't have an answer. Not the fuel pump/filter.....and they have eliminated ignition problems.........any ideas?

    Thank you! I will pass that along to the mechanic.The mechanic hasn't really come up with anything, I guess because they can't get it to act up on them too much and the computer is not detecting anything. no errors. Thank you for the quick response!

This is usually caused by a spark plug not sparking. It could be a spark plug, a spark plug wire, or low compression on 1 cylinder. Your check engine light should be on. You can take it to Autozone and have them put it on their scanner and the diagnostic printout will tell you where the mis-fire is at. You can also usually see spark at night time with the hood open in the dark, if it is a spark plug wire.

Sounds like your IAC(idle air control) motor needs to be replaced. its on the bottom side of the throttle body. there are 3 phillips head screws holding it on.

01 grand am stalled in water now won t start


the engine may have ingested some water through the exhaust. pull the spark plugs and check to see if there is any water in the cylinders, also you need to change your oil as water may have gotten into it.
